What does a green arrow traffic light indicate?

A green arrow traffic light signifies that you may proceed in the direction of the arrow. It indicates that the movement in the pointed direction is permitted, and drivers should also be aware of and yield to any pedestrians who may be crossing at that intersection. This means that while you are allowed to move forward, you still have the responsibility to ensure the safety of pedestrians before you continue.

The other options do not reflect the meaning of a green arrow. For instance, a stop and wait requirement would be applicable for a red light or a stop sign, but not for a green arrow. Making a U-turn is typically a separate maneuver that may have different signals or signage. Lastly, while a green arrow does give a driver the right of way to proceed, it does not eliminate the need to yield to pedestrians, which is a critical aspect of safely navigating intersections.
